This is the U.S. National Phase application of PCT/JP2020/033107, filed Sep. 1, 2020, which claims priority to Japanese Patent Application No. 2019-165185, filed Sep. 11, 2019, the disclosures of each of these applications being incorporated herein by reference in their entireties for all purposes.

FIELD OF THE INVENTION

The present invention relates to a protective garment.

BACKGROUND OF THE INVENTION

Some protective products have various forms and functions depending on their purposes and uses. Among them, there are protective products that have excellent performances aimed at protection from harmful substances that may have an adverse effect on a human body, such as a blood and a virus, that is, excellent blood barrier property and virus barrier property. However, this protective product is excellent in blood barrier property and virus barrier property, though it has a poor water vapor permeability, inside of which becomes highly humid due to sweating generated from the body, leading to a problem for improvement in comfortability of clothing such as feelings of heat and stuffiness.

Here, a protective garment using a functional fabric, which has excellent virus barrier property and blood barrier property (which, hereinafter, may be collectively referred to as a barrier property) and an excellent water vapor permeability, is known (see Patent Document 1). This functional fabric has a laminated structure of a microporous film having a large number of fine through holes with a non-woven fabric.

PATENT DOCUMENT

Patent Document 1: WO 2017/119355

SUMMARY OF THE INVENTION

Meanwhile, at the time of wearing the protective garment, a movement of a wearer's elbow is large. However, the microporous film comprising the functional fabric of Patent Document 1 has a high bending resistance. Therefore, bending resistance of the functional fabric is also high. As a result, the protective garment using the functional fabric having a high bending resistance easily causes resistance to the movement of the elbow when the wearer moves the elbow, easily reducing workability.

In view of the circumstances described above, it is an object of the present invention to provide a protective garment having excellent water vapor permeability, barrier property, and also workability.

The protective garment according to embodiments of the present invention for solving the above-described problems is a protective garment comprising a pair of sleeve parts and a body part, wherein the protective garment has a first fabric and a second fabric and comprises one or more joint covering parts covering at least one of wearer's elbow joint or knee joint, wherein the first fabric has a water vapor permeability of 200 g/m²/hr or more, a virus barrier property of class 4 or higher, a blood barrier property of class 4 or higher, and a bending resistance of 60 mm or more and 110 mm or less, wherein the second fabric is arranged on the joint covering part and has a virus barrier property of class 4 or higher, a blood barrier property of class 4 or higher, and a bending resistance of 20 mm or more and 50 mm or less, and wherein a surface area of the first fabric with respect to a total surface area of the protective garment is 15% or more and 70% or less.

DETAILED DESCRIPTION OF EMBODIMENTSOF THE INVENTION First Embodiment

The protective garment according to one embodiment of the present invention comprises a pair of sleeve parts and a body part. The protective garment has a first fabric and a second fabric. The protective garment comprises one or more joint covering parts covering at least one of a wearer's elbow joint or knee joint. The first fabric has a water vapor permeability of 200 g/m²/hr or more, a virus barrier property of class 4 or higher, a blood barrier property of class 4 or higher, and a bending resistance of 60 mm or more and 110 mm or less. The second fabric is arranged in the joint covering part and has a virus barrier property of class 4 or higher, a blood barrier property of class 4 or higher, and a bending resistance of 20 mm or more and 50 mm or less. A surface area of the first fabric with respect to a total surface area of the protective garment is 15% or more and 70% or less.

The first fabric has a high barrier property and also has a high water vapor permeability. Meanwhile, the first fabric having a high barrier property and a high water vapor permeability tends to become hard with a bending resistance of 60 mm or more and 110 mm or less due to composition of the fabric. On the other hand, the second fabric has a high barrier property and is a flexible fabric. Meanwhile, a water vapor permeability of the second fabric, which has a high barrier property and is flexible, is lower than that of the first fabric. This is due to composition of the second fabric. In the protective garment of this embodiment, the first fabric having a high barrier property and a high water vapor permeability occupies 15% or more and 70% or less of the total surface area of the protective garment, and further the second fabric having a high barrier property and is flexible is arranged on one or more joint covering parts. Therefore, the protective garment of this embodiment is excellent in water vapor permeability, barrier property, and also workability.

In this embodiment, for the sake of clarity, a case is exemplified where the protective garment of this embodiment is worn by a wearer with a height of 171 cm, an upper arm length of 32 cm, a cervical/acromion straight line distance of 15 cm, a fossa jugularis height of 140 cm, a midpoint height of a sternum of 128 cm, an anterior axillary width of 34 cm, a straight line distance between angulus inferior scapulae of 20 cm, a thigh length of 44 cm, and a tibial upper margin height of 43 cm.

Moreover, in this embodiment (first embodiment), exemplified is an aspect where the joint covering part has a part A that covers an elbow joint of a wearer's right arm and a part B that covers an elbow joint of the wearer's left arm at the time of wearing the protective garment and the second fabric is arranged on the part A and the part B.

The part A and the part B are parts of the protective garment that cover the wearer's elbow joint when worn. Accordingly, the part A and the part B of the protective garment are parts where, when the wearer bends and stretches the elbow, the fabric of the protective garment bends according to the movement of the bending and stretching of the wearer's elbow. Therefore, by using fabric having an excellent flexibility which is a second fabric for the part A and the part B, the protective garment improves in workability of the wearer when worn. That is, the protective garment is excellent in workability.

As such, in the protective garment of this embodiment, fabric having a high water vapor permeability is arranged on a part of the protective garment, while fabric having a high flexibility is arranged on another part of the protective garment that covers a part where the wearer moves a lot. Therefore, the protective garment can achieve both comfortability and workability when worn at a high level.

It is preferable that the protective garment of this embodiment comprises a part C that covers the wearer's greater pectoral muscle at the time of wearing the protective garment and that the first fabric is arranged on the part C. In a human body, there are many important organs for the human body such as a heart and lungs near a greater pectoral muscle. Accordingly, it is said that the wearer easily feels heat more sensitively in the greater pectoral muscle and parts around the greater pectoral muscle compared with parts other than these parts. Moreover, in the human body, the body temperature decreases due to the temperature being taken from the skin as sweat evaporates. However, it is known that the higher the humidity becomes, the less likely sweat evaporates when the human body sweats, so that the human body feels hot when the temperature is high. Therefore, by using fabric having a high water vapor permeability which is a first fabric for the part C, the protective garment can approximate humidity in the vicinity of the wearer's greater pectoral muscle to humidity of an outside air. As a result, the protective garment of this embodiment is more excellent in comfortability.

Moreover, it is preferable that the body part comprises a part D that covers the wearer's subscapular muscle at the time of wearing the protective garment and that the first fabric is arranged on the part D. In a human body, there are many important organs for the human body such as a heart and lungs near a subscapular muscle. Accordingly, it is said that the wearer easily feels heat more sensitively in the subscapular muscle and parts around the subscapular muscle compared with parts other than these parts. Therefore, by using fabric having a high water vapor permeability which is a first fabric for the part D, the protective garment can approximate humidity in the vicinity of the wearer's subscapular muscle to humidity of the outside air. As a result, the protective garment of this embodiment is more excellent in water vapor permeability and more excellent in comfortability to be felt by the wearer.

It is preferable that the protective garment further comprises a hood, the body part and the hood are integrated, and at least a part of the hood is composed of a first fabric. The hood is a part that covers the wearer's head at the time of wearing the protective garment. Since a brain is present in the wearer's head, it is said that the wearer's head feels heat more sensitively compared with sites other than the wearer's head. Therefore, by using fabric having a high water vapor permeability which is a first fabric for the hood, the protective garment can approximate humidity in the wearer's protective garment to humidity of the outside air. As a result, the protective garment of this embodiment is more excellent in comfortability to be felt by the wearer.

When the protective garment comprises a hood, it is preferable that the protective garment has the body part and the hood integrated. When the body part and the hood are separated, the protective garment easily forms a gap between the body part and the hood. In this case, in order to prevent the occurrence of the gap described above, it is necessary to provide a large number of parts where the body part and the hood overlap with each other to prevent the gap in the protective garment. On the parts where the body part and the hood overlap with each other, the water vapor permeability easily decreases, and also the flexibility easily decreases. On the other hand, in the protective garment in which the body part and the hood are integrated, there is no gap between the body part and the hood, and there is no part where the body part and the hood overlap with each other. Therefore, the protective garment is more excellent in comfortability and workability when worn.

The protective garment of this embodiment may further comprise a lower part of the garment. In this case, it is preferable that the protective garment has, as joint covering parts, a part E that covers a knee joint of the wearer's right leg and a part F that covers a knee joint of the wearer's left leg at the time of wearing the protective garment and that the second fabric is arranged on the part E and the part F.

The part E and the part F are parts where the fabric of the protective garment bends when the wearer bends and stretches the knee. Therefore, by using a flexible fabric which is a second fabric for the part E and the part F, the protective garment further improves in workability of the wearer at the time of wearing the protective garment.

When the protective garment comprises a lower part of the garment, it is preferable that an upper part of the garment and the lower part of the garment are integrated in the protective garment. A protective garment, in which the upper part of the garment and the lower part of the garment are separated, easily forms a gap between the upper part of the garment and the lower part of the garment when the upper part of the garment and the lower part of the garment are worn. In this case, in order to prevent the occurrence of the gap described above, it is necessary to provide a large number of parts where the upper part of the garment and the lower part of the garment overlap with each other to prevent the gap in the protective garment. On the parts where the upper part of the garment and the lower part of the garment overlap with each other, the water vapor permeability easily decreases, and also the flexibility easily decreases. On the other hand, in the protective garment in which the upper part of the garment and the lower part of the garment are integrated, there is no gap between the upper part of the garment and the lower part of the garment, and there is no part where the upper part of the garment and the lower part of the garment overlap with each other. Therefore, the protective garment is more excellent in comfortability and workability when worn.

(First Fabric)

Next, each fabric constituting the protective garment of this embodiment will be described. The first fabric has a water vapor permeability of 200 g/m²/hr or more. The water vapor permeability of the first fabric is preferably 350 g/m²/hr or more, more preferably 450 g/m²/hr or more. Moreover, the water vapor permeability of the first fabric is preferably 600 g/m²/hr or less, more preferably 500 g/m²/hr or less. When the water vapor permeability of the first fabric is 200 g/m²/hr or more, humidity inside the protective garment can be kept low at the time of wearing the protective garment. As a result, the protective garment is excellent in comfortability.

A method of adjusting the water vapor permeability of the first fabric within the above-described ranges is not particularly limited. By way of an example, the water vapor permeability of the first fabric can be adjusted by varying thickness, porosity, etc. of a microporous film constituting the first fabric.

The first fabric has a virus barrier property of class 4 or higher. The virus barrier property is preferably class 5 or higher, more preferably class 6.

A method of adjusting the virus barrier property of the first fabric within the above-described ranges is not particularly limited. By way of an example, the virus barrier property of the first fabric can be adjusted by increasing thickness of or decreasing porosity of a microporous film constituting the first fabric.

The first fabric has a blood barrier property of class 4 or higher. The blood barrier property is preferably class 5 or higher, more preferably class 6. When the blood barrier property is class 4 or higher, the protective garment is excellent in barrier property.

A method of adjusting the blood barrier property of the first fabric within the above-described ranges is not particularly limited. By way of an example, the blood barrier property of the first fabric can be adjusted by increasing thickness of or decreasing porosity of a microporous film constituting the first fabric.

In this embodiment, the virus barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8061 (2010) (corresponding to ISO16604:2004) to obtain a pressure value to be the maximum (maximum pressure) among pressures by which a virus does not permeate. Next, the obtained maximum pressure value is classified using the criteria for resistance-to-bacteriophage permeability shown in JIS T8122 (2007) (corresponding to EN14126:2003). This defines virus barrier properties (classes 1-6). Moreover, in this embodiment, the blood barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8060 (2007) (corresponding to ISO16603:2004) to obtain a pressure value to be the maximum (maximum pressure value) among pressures by which a blood does not permeate. Next, the obtained maximum pressure value is classified using the criteria for resistance-to-artificial blood permeability shown in JIS T8122 (2007) (corresponding to EN14126:2003). This defines blood barrier properties (classes 1-6).

The first fabric has a bending resistance of 60 mm or more. The bending resistance is preferably 80 mm or more, more preferably 90 mm or more. Moreover, the bending resistance is 110 mm or less. The bending resistance is preferably 105 mm or less, more preferably 100 mm or less. When the bending resistance is within the above-described ranges, the protective garment becomes soft and improves in workability.

A method of adjusting the bending resistance of the first fabric within the above-described ranges is not particularly limited. For the first fabric of the protective garment of this embodiment, a microporous film having a porosity of 30% or more and 60% or less and a thickness of 5 μm or more and 50 μm or less is preferably used as described later in order to realize a high barrier property and a high water vapor permeability. Here, the first fabric using such a microporous film tends to become hard. Therefore, the bending resistance of the first fabric is easily adjusted to 60 mm or more. Besides, the bending resistance of the first fabric can be adjusted to become as desired to some extent by a method of adjusting porosity, thickness, etc. of the microporous film, or by a method of adjusting composition of an adhesive layer between layers when the microporous film is a laminated body of a plurality of microporous film layers. In order for the first fabric to realize a water vapor permeability of 200 g/m²/hr or more, a virus barrier property of class 4 or higher, and a blood barrier property of class 4 or higher, the bending resistance of the first fabric is easily adjusted to 60 mm or more. On the other hand, the smaller the bending resistance of the first fabric is, the more flexible the protective garment becomes. Therefore, an upper limit of the bending resistance of the first fabric is preferably 110 mm or less.

In this embodiment, the microporous film refers to a film having a large number of pores and having a porosity of 5% or more. Moreover, a nonporous film refers to a nonporous film having no pores as those the microporous film has and a film having substantially no pores. The film having substantially no pores refers to a film having a porosity of less than 5%.

Resin constituting the microporous film is not particularly limited. By way of an example, resin is a polyolefin resin, polycarbonate, polyamide, polyimide, polyamideimide, aromatic polyamide, a fluorine-based resin, or the like. Among them, resin is preferably a polyolefin resin from the viewpoints of heat resistance, moldability, reduction of production cost, chemical resistance, oxidation resistance/reduction resistance, and the like.

A monomer component constituting the polyolefin resin is not particularly limited. By way of an example, the monomer component is a compound having a carbon-carbon double bond such as ethylene, propylene, 1-butene, 1-pentene, 3-methylpentene-1,3-methyl-1-butene, 1-hexene, 4-methyl-1-pentene, 5-ethyl-1-hexene, 1-heptene, 1-octene, 1-decene, 1-dodecene, 1-tetradecene, 1-hexadecene, 1-heptadecene, 1-octadecene, 1-eicosene, vinylcyclohexene, styrene, allylbenzene, cyclopentene, norbornene, and 5-methyl-2-norbornene, or the like. The polyolefin resin may be a homopolymer of the above-described monomer component, may be a copolymer composed of at least two kinds selected from the group consisting of the above-described monomer components, or may be a composition, etc. blended with a homopolymer or a copolymer.

In addition to the above-described monomer components, the polyolefin resin may be copolymerized and/or graft-polymerized with, for example, vinyl alcohol, maleic anhydride, and the like.

The polyolefin resin is preferably polyethylene or polypropylene. The polyolefin resin is preferably polypropylene from the viewpoints of heat resistance, air permeability, porosity, and the like. In this case, it is preferable that a main component of the constituent resin of the microporous film is polypropylene. Besides, in this embodiment, the “main component” means that a ratio of a specific component to all components is 50% by mass or more. In this embodiment, the microporous film has polypropylene in an amount of preferably 80% by mass or more, more preferably 90% by mass or more, further preferably 95% by mass or more.

A method of forming through holes, which are pores, in the microporous film is not particularly limited. By way of an example, the method of forming through holes may be either by a wet process or a dry process.

In the first fabric, the porosity of the microporous film is preferably 30% or more, more preferably 40% or more. Moreover, in the first fabric, the porosity of the microporous film is preferably 60% or less, more preferably 50% or less. When the porosity is within the above-described ranges, the first fabric is more excellent in both barrier property and water vapor permeability.

The first fabric may have a fiber layer in addition to the microporous film, since the fiber layer provides other necessary physical properties such as, for example, puncture strength, tensile strength, and water pressure resistance.

Examples of the fiber layer include a fiber structure such as a woven fabric, a knitted fabric, a non-woven fabric, and paper. Among them, the fiber layer is preferably a non-woven fabric from the viewpoints of excellent cost efficiency, tensile strength, etc. The non-woven fabric is not particularly limited. By way of an example, examples of the non-woven fabric appropriately include a wet non-woven fabric, a resin bond type dry non-woven fabric, a thermal bond type dry non-woven fabric, a spunbond type dry non-woven fabric, a needle punch type dry non-woven fabric, a water jet punch type dry non-woven fabric, a flash spinning type dry non-woven fabric, as well as a non-woven fabric produced by a paper-making method capable of making basis weight and thickness uniform. Among them, as the non-woven fabric, a spunbond type dry non-woven fabric is preferable from the viewpoints of cost, tensile strength, etc.

A material of the fiber layer is not particularly limited. By way of an example, examples of the material of the fiber layer include polyolefin such as polyethylene and polypropylene, polyester such as polyethylene terephthalate and polylactic acid, polycarbonate, polystyrene, polyphenylene sulfide, a fluorine-based resin, and a mixture thereof, etc. Moreover, examples of forms of fibers using a mixture of two or more components may include fibers using a copolymer of two or more kinds of resin, mixed fibers in which a fiber composed of a plurality of single components is present as a non-woven fabric, and fibers having a plurality of components per fiber such as core-sheath type, sea-island type, and side-by-side type fibers.

A method of partially joining a microporous film and a fiber layer is not particularly limited. By way of an example, examples of the joining method include an embossing process of pressing with a roll carved with concave and convex and a pair of rolls and applying heat to these rolls by heating, ultrasonic waves, or high frequency to perform a partial adhesion, a sinter process of spraying with a powder having an adhesive component of a low melting point and conducting a heat treatment to perform a partial adhesion, a hot melt process of spraying with a hot melt adhesive or the like to partially make a water-vapor permeable film and a fiber layer to adhere to each other, and the like. Moreover, a method of applying an adhesive or the like to the entire surface of the microporous film or the fiber layer by coating or the like and laminating it is not preferable because the water vapor permeability is impaired.

A total area of the first fabric is 15% or more, preferably 20% or more, more preferably 30% or more, with respect to a total area of the protective garment. Moreover, the total area of the first fabric is 70% or less, preferably 60% or less, more preferably 40% or less, with respect to the total area of the protective garment. The protective garment may provide a wearer with a more excellent comfortability when the total area of the first fabric is equal to or greater than the above-described lower limit value. On the other hand, the protective garment may provide the wearer with a more excellent workability when the total area of the first fabric is equal to or lower than the above-described upper limit value.

(Second Fabric)

The second fabric has a bending resistance of 20 mm or more. The bending resistance is preferably 30 mm or more. Moreover, the bending resistance is 50 mm or less. The bending resistance is preferably 40 mm or less.

A method of adjusting the bending resistance of the second fabric within the above-described ranges is not particularly limited. In the second fabric of the protective garment of this embodiment, the bending resistance can be adjusted to 20 mm or more and 50 mm or less by setting porosity of a nonporous film to less than 5% and setting thickness of the nonporous film to 50 μm or more and 300 μm or less when the second fabric is a nonporous film.

Moreover, the bending resistance of the second fabric can be increased by increasing the thickness of the second fabric and can be decreased by decreasing the thickness of the second fabric. Furthermore, the bending resistance can also be adjusted by adjusting flexibility of a material by a known means.

When the bending resistance of the second fabric is equal to or lower than the above-described upper limit value, the protective garment easily follows movement of a wearer's body, easily improving workability. Moreover, when the bending resistance of the second fabric is equal to or greater than the above-described lower limit value, in the protective garment, when the wearer sweats while working, the second fabric is less likely to cling to the wearer's body, which easily suppresses a decrease in workability.

The second fabric has a virus barrier property of class 4 or higher. The virus barrier property is preferably class 5 or higher, more preferably class 6. When the virus barrier property is class 4 or higher, the protective garment is excellent in barrier property.

A method of adjusting the virus barrier property of the second fabric within the above-described ranges is not particularly limited. By way of an example, when the second fabric is a nonporous film, the barrier property can be improved by increasing thickness of the nonporous film or decreasing porosity of the nonporous film.

The second fabric has a blood barrier property of class 4 or higher. The blood barrier property is preferably class 5 or higher, more preferably class 6. When the blood barrier property is class 4 or higher, the protective garment is excellent in barrier property.

A method of adjusting the blood barrier property of the second fabric within the above-described ranges is not particularly limited. By way of an example, the blood barrier property of the second fabric can be adjusted by increasing thickness of or decreasing porosity of a microporous film constituting the second fabric.

In this embodiment, the virus barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8061 (2010) (corresponding to ISO16604:2004) to obtain a pressure value to be the maximum (maximum pressure) among pressures by which a virus does not permeate. Next, the obtained maximum pressure value is classified using the criteria for resistance-to-bacteriophage permeability shown in JIS T8122 (2007) (corresponding to EN14126:2003). This defines virus barrier properties (classes 1-6). Moreover, in this embodiment, the blood barrier property is defined by the following method. First, a test is performed by the D method defined by JIS T8060 (2007) (corresponding to ISO16603:2004) to obtain a pressure value to be the maximum (maximum pressure value) among pressures by which a blood does not permeate. Next, the obtained maximum pressure value is classified using the criteria for resistance-to-artificial blood permeability shown in JIS T8122 (2007) (corresponding to EN14126:2003). This defines blood barrier properties (classes 1-6).

A material of the second fabric is not particularly limited. By way of an example, as the material of the second fabric, a material used as a known waterproof fabric such as polyvinyl chloride (PVC), polyurethane, polyethylene, and ethylene vinyl acetate copolymer can be used. By using a nonporous film made of these materials as the second fabric, a second fabric having an excellent blood barrier property and an excellent virus barrier property becomes easily obtained. Besides, when the second fabric is a nonporous film, in the second fabric, the above-described barrier property becomes easily obtained by setting the porosity of the nonporous film to less than 5% and setting the thickness of the nonporous film to 50 μm or more.

The porosity of the second fabric is preferably less than 5%, and it is more preferable that the second fabric is substantially nonporous. When the porosity is within such a range, the second fabric easily improves in bending resistance, blood barrier property, and virus barrier property at the same time.

The water vapor permeability of the second fabric is preferably lower than that of the first fabric. That is, when the second fabric is made of a nonporous film in order to obtain excellent barrier property and flexibility, the water vapor permeability of the second fabric becomes lower than that of the first fabric. The water vapor permeability of the second fabric is preferably 0 g/m²/hr or more, more preferably 5 g/m²/hr or more. Moreover, the water vapor permeability of the second fabric is preferably 100 g/m²/hr or less, more preferably 10 g/m²/hr or less. Even if the water vapor permeability of the second fabric is 0 g/m²/hr, the protective garment of this embodiment comprises a first fabric having an excellent water vapor permeability, so that the humidity inside the protective garment during wearing can be kept low. As a result, the protective garment improves in comfortability. Besides, a method of adjusting a water vapor permeability of a second fabric is not particularly limited. By way of an example, the water vapor permeability of the second fabric can be adjusted by varying the porosity and thickness of the nonporous film when the second fabric is a nonporous film.

A total area of the second fabric is preferably 30% or more, more preferably 40% or more, further preferably 60% or more, with respect to a total area of the protective garment. Moreover, the total area of the second fabric is preferably 85% or less, more preferably 80% or less, further preferably 70% or less, with respect to the total area of the protective garment. The protective garment may provide a wearer with a more excellent workability when the total area of the second fabric is equal to or greater than the above-described lower limit value. On the other hand, the protective garment may provide the wearer with a more excellent comfortability when the total area of the second fabric is equal to or lower than the above-described upper limit value.

Second Embodiment

In the above-described first embodiment, the protective garment was exemplified which has the part A that covers the elbow joint of the wearer's right arm and the part B that covers the elbow joint of the wearer's left arm and has the part E that covers the knee joint of the wearer's right leg and the part F that covers the knee joint of the wearer's left leg, at the time of wearing the protective garment, as the joint covering parts. Instead, the protective garment of the present invention may have a part E that covers a knee joint of the wearer's right leg and a part F that covers a knee joint of the wearer's left leg as joint covering parts and may not have a part A that covers an elbow joint of the wearer's right arm and a part B that covers an elbow joint of the wearer's left arm.
